After reading countless reviews and comparing several models, I chose the De'Longhi Dragon Digital Oil Filled Radiator Heater for its energy efficiency and modern design. Having used it for two weeks, I'm impressed with how quickly it heats up my medium-sized living room; within 15 minutes, the temperature rose by about five degrees Fahrenheit. The digital interface is intuitive and offers precise control over temperature settings. However, while the heater itself is quiet, the thermostat fan kicks in occasionally with a noticeable hum when temperatures fluctuate. It's not disruptive to sleep or concentration, but it's something I've noticed nonetheless. Overall, this heater has been a welcome addition during these chilly evenings.
